Sit and Go ICM Analysis.

Yeah, hand 28 I mentioned I must have been tilting a little after the KQs hand. Should have shoved there for sure.

Hand 35 is a little funky. With my stack and the blinds, my M was orange (8 ). The fold was kinda weird with 7:1 pot odds. My decision to fold was based on three factors other than pot odds (which were huge)

The first was read. I raised UTG and yet I am being min raised by the button. He is practically begging for a call, so mostly that is going to be a very big hand.

The second is playability. The button has taken the lead and unless I feel like going all in with A6, then he will have the lead and position. I am never going to know where I stand with A6 unless I flop ridiculously huge. I am getting close to correct odds to try for a huge flop, but I do have to consider the next issue....

The third reason is equity. If I fold now, I have 18882 chips which can do some pretty serious damage to every stack at the table. If I call and then fold a flop (by far the most likely event) I will have 1200 chips. That leaves me as one of the short stacks. and it leaves me in a position where I can be bullied a lot more. The overriding factor here is the limited number of total chips in play, compared to an MTT. Losing 400 chips means a lot in a SNG because it represents a much higher proportion of total chips in play.

This is reflected in sit and go ICM analysis. ICM really doesn't apply much in MTTs, however in SNGs, the chips you currently have are worth more than the chips you hope to win. So I don't know what the ICM adjusted post odds would be, but they are way less than 7:1

I again go back to Harrington that poker is about finding the best balance between all factors. Pot odds was a compelling factor to call that raise. However on balance with all other factors, I decided it was not enough.

Hand 40 is probably just my weird way of appraising hand strength. Ace rag UTG at a 5 handed table is a pretty crap hand. I have to get through 4 players. The more players I have to get through the more chance one of them has an Ace, in which case I am dominated. I would much rather be shoving 56s UTG or A5o from the button. As mentioned above, I also wanted to give UTG+1 a chance to shove into one of the big stacks and hang himself with a hand he would not have called a shove with

A7s was a similar situation, although this is much more questionable in my mind. Primarily it was stack sizes and position which prompted me to fold.

One of the things I try to keep in mind on the bubble is "don't bubble and don't do anything to prevent someone else from bubbling".

Here I would have been shoving into the big stack's blind which is not that much fun. Secondly, if I fold, then perhaps the short stack will shove his button into the big stack BB. If I shove then alot of his marginal hands that he would himself shove, he now folds. So rather than be guided too much by card strength (which was pretty good) I decided to ensure that I avoided bubbling and gave the button every chance to bubble himself. As Raziel points out however, it was a bad fold. I accept his opinion on all things SNG.

Problem is, given the same situation a second time round, I think I would still talk myself into folding. And that is a problem and probably a big part of the reason why I really do suck at SNGs.

Hand 64 - same again. I would be shoving 67s, but I fold A5o. I'm a strange puppy.

You are right though, that I do play loose in MTTs and probably overly tight in SNGs, especially near the bubble. My loose play in MTTs is intuitively easy for me to rationalize. They payouts stupendously favour a win and you can afford to bust out of hundreds of them pursuing that win. That means you can be pretty crazy and still make very big money. In fact I argue, you cannot make very big money in MTTs unless you are prepared to gamble (at the appropriate time). In SNGs, you need to be making the money at least 40% of the time. To me that means you can't afford to gamble as much. Especially on the bubble.

I have not played enough Poker Stars SNGs to really know.

In fact Even if I had played loads of poker stars SNGs, I still wouldn't know. I built my poker bankroll initially playing SNGs up to $50 buy-ins. I then started concentrating on MTTs and ever since then I have not been able to play sit and goes properly. My risk tolerances are all mucked up and I am folding when I should be shoving too much.

I've literally been struggling with this problem for about a year. I am not bursting at the seems to fix it tomorrow, but I do find it curious
